There are some wonderful or unknown things about smart phones that many people may not know.

Assalamu Alaikum, 

I hope everyone is doing well; I'm going to stop talking now.
A smartphone is a handheld computer or phone that runs on a mobile operating system such as iOS or Android. Smartphones are often pocket-sized to make them easier to transport.

There are also tablets, which are somewhat bigger versions of cellphones. Color screens span 60% to 8% of the front of the smartphone, with a touch screen interface that allows all types of actions, such as typing on a virtual keyboard and starting applications by tapping application icons, to be conducted by touch on the screen.

History:

Nokia Tesla and Theodore Paraskevaks were the first to conceive the notion of merging phone and computing systems in 1909 and 1981, respectively. It was first released in 1993 after being patented in 1974. NTT Docomo, a Japanese corporation, originally produced smartphones in 1999 with a data transfer speed of 9.8 kilobits per second and a tiny screen.

Operating system:

Symbian was the most popular operating system. In 2006, Nokia released the Symbian device, as well as Windows and Blackberry smartphones. APPLE released its first large-screen smartphone in 2006, which was appealing and included the first multitouch interface. The first Android OS-enabled phone, the HTC Dream, debuted the open-source platform in 2006. Andy Rubin designed the Android operating system, which was eventually acquired by Google and is now widely used. Smartphone operating systems include Android, iOS, Windows 10, and others. Operating systems such as Blackberry OS, Windows, Firefox, Bada, Web OS, Palm, Ubuntu Touch, and others, on the other hand, have been disabled.
People's cell phones have become an inseparable part of their lives in recent years. This is due to the fact that the smartphone now includes all of the functions and applications that we use on a daily basis. We use this smartphone for a variety of things, including talks, video chats, photos, social media, the internet, email, GPS tracking, and compass navigation. It is also becoming increasingly vital for us as a result of various tools driven by various sensors. Some high-end phones now come with air pressure and heart rate monitors, as well as security sensors.

Its importance in our human civilization is growing by the day, as most individuals spend practically all of their time on social media sites like Facebook and Twitter. Furthermore, its varied applications make individuals aware of the need for it on a daily basis.
